Answer: y=-61/2
Step-by-step explanation: - 4(8 + y)/-4 = 90/-4
8+y-8=-45/2-8
-8(2)-45/2
-16-45
-61
y=-61/2
If you flipped a coin 3 times:{
Total number of possible outcomes = 2³ = 8
Total number of outcomes with at least 2 tails = 4
{HTT , THT, TTH, TTT}
P(at least 2 tails ) = 4/8 = 1/2
Answer: 1/2
Answer:
75 degrees
Step-by-step explanation:
30 + 75 = 105
180 - 105 = 75
Answer:
B
Step-by-step explanation:
All you have to basically do on this one is go backwards.
The beginning equation is 4x+4=12, so to first revesre the adding we are going to use 12, the product, and subtract 4 from it (since that is what was added).
12-4=8
Now you need to reverse the times 4, so to do that just divide instead because that is the invese of multiplication.
8/4=2
Now you have 2, which is the variable, x. To make sure this is right you can just put it into the equation and see if 4x2+4 is 12
Hope this helped!
Y=(x+9)(x-3)+c
∵(-3,-36)lies on it.
-36=(-3+9)(-3-3)+c
-36=(-6)(-6)+c
-36=36+c
c=-36-36=-72
y=(x-9)(x+3)-72
y=x^2+3x-9x-27-72
y=x^2-6x-99
